Abstract
Techniques for control signaling in extreme high throughput (EHT) environments are described. A message transmitted by an access point (AP) may allocate resources to a plurality of stations (STAs). The AP may be configured to allocate up to 320 MHz of total bandwidth or up to sixteen spatial streams to one or more STAs. In some multiple-user multiple-input multiple-output (MU-MIMO) cases, the spatial configuration field may include a starting spatial stream field and a spatial stream number field. In some non-MU-MIMO cases, the spatial configuration field may be expanded by one bit or more. In some cases, content channels of a resource unit (RU) allocation table may span a frequency segment of 40 MHz.
